Sisira JamesHe holds BE, MSc and PhD degrees from Bangalore University, University of Aberdeen, and University of Waikato, respectively. His PhD thesis was on Surge Propagation studies under the supervision of the first two authors of this work, and his MSc thess was on Computer Simulation of DC-DC Switching Converter Systems. He has developed mathematical models for nonlinear surge protection devices and employed MATLAB-based numerical simulations to predict the incipient failure of electronics in transient voltage suppressor systems (TVSSs). He has also validated the numerical simulations experimentally using a lightning surge simulator. Sisira James has served Sri Lanka Telecom PLC as a senior telecommunications professional for more than 11 years. Read More Read Less
